Holland dam
Holland
Holland, located in Orange County, Vermont, is a privately owned earth dam built in 1966 by the USDA NRCS for recreational purposes. The dam stands at 27 feet tall and stretches 224 feet in length, with a storage capacity of 24 acre-feet. It is regulated by the Vermont Department of Environmental Conservation and undergoes regular inspections to ensure its safety and compliance with state regulations.
Despite being rated as having a significant hazard potential, Holland has not received a condition assessment as of yet. The spillway type is categorized as uncontrolled, with a spillway width of 0 feet. While the dam has not been modified in recent years, its risk assessment is considered moderate. Emergency action plans and risk management measures are not currently in place, indicating a need for further preparedness and mitigation strategies to address potential safety concerns.
For water resource and climate enthusiasts, Holland presents an intriguing case study of a privately owned dam in Vermont. Its design and construction by the USDA NRCS, along with its regulatory oversight by the state, highlight the importance of maintaining and monitoring infrastructure for both recreational and safety purposes. As Holland continues to be a focal point for water management in the region, there is a clear opportunity for stakeholders to enhance emergency preparedness and risk management measures to ensure the long-term sustainability of this vital water resource.
Dam data reference
Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About Holland
Where does the data for Holland come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
